From Ohhh Lulu:
The Ruffle Thong is easy and quick to sew - AND is a great way to use up those cute, printed cotton scraps. This pattern uses only 1/2 yard of fabric plus a small piece of cotton jersey.
This is an easy pattern that requires basic knowledge of bias cuts, and how to ruffle using elastic.
